Castro works for both very large and smaller companies and organisations. Some examples:

ONL voor Ondernemers | Communications

Business organisation ONL voor ondernemers requested Castro's assistance in regards to communications support. The main work included live broadcasts during the Lower House campaign, podcasts, articles and social media management:

"ONL is of course the voice of entrepreneurs in the Netherlands. We want that voice to be very well heard. We sought support for that. Castro has filled that role fantastically. We worked together wonderfully!"

Hans Biesheuvel | Chairman ONL voor Ondernemers

SpiritsNL | Communications & Lobby

SpiritsNL is the trade association of spirits producers, with members such as A Brand New Day, Lucas Bols and Hooghoudt. Since 2021, we have been supporting SpiritsNL with their communications, especially aimed at political-administrative stakeholders.

"We engaged Castro for our 'Laten We Het Gezellig Houden' campaign. That's a campaign where we target decision- & policy-makers in The Hague. Castro has the knowledge and expertise to help us do that the right way."

Joep Stassen | Director SpiritsNL

Pathé | Lobby

Pathé engaged Castro for stakeholder liaison support, with a focus on the theaters' immediate surroundings:

"For a company like Pathé, it is important to have good contacts with the surrounding area of our theaters. We asked Castro Communications to guide our theater managers in this regard. The main message from Stefan and Frits: "Make friends when you don't need them yet." Our managers have received many useful tips and are very enthusiastic."

Jacques Hoendervangers | CEO Pathé Netherlands

Gilat Foundation | Communications

Making children in hospitals forget for a moment that they are sick. That is the goal of Gilat Foundation, interactive theater for children in academic children's hospitals. Almost immediately after Castro Communications started in 2019, we started helping Stichting Gilat with their communications. The foundation is now active in Amsterdam, Rotterdam, The Hague, Utrecht, Nijmegen and on Curaçao.

"Gilat Foundation has the dream of providing interactive theater to all sick children in the Netherlands and in the Caribbean part of the Kingdom. Castro has been very involved in helping us for years with contacts with the government and putting our foundation well on the map."

Jair Eisenmann | Chairman Gilat Foundation

Uber | Communications

Uber requested Castro Communications for support in the field of (corporate) communications. We have been assisting Uber with strategy, communications and media since 2021.

"I have come to know Castro as a very hands-on agency in that they are always accessible and quick to respond. It is nice to spar with Castro on strategy and they have an excellent network."

Rick Janse Kok | Uber, Head of Communications Northern Europe

Flink | Communications & Lobby

Flink delivers groceries quickly that can be ordered online through its app or website. The "flash delivery company" engaged Castro Communications in late 2021 for communications support and liaison with governments.

"Flink has become very popular in a short period of time. We have a lot of contact with the environment of our hubs, the media and the government. Castro is helping us with that excellently. Fast and pragmatic."
